Document Summary
Learning: behavioral processes, when similar stimuli predict similar consequences, when similar stimuli predict different consequences, when dissimilar stimuli predict the same consequence, brain substrates, cortical representations and generalization, generalization and the hippocampal region. Discriminate: need to respond to stimuli that are completely novel, rather than respond randomly, use prior experience with stimuli we have encountered. Two basic ways of using these past experiences: Using the past to cope with the present. Discriminate: the right balance, specificity: applying the past narrowly; discriminating, generality: applying the past broadly; generalizing. Generalization in learning: sensitization: chapter 3, classical conditioning: chapter 4, operant conditioning: chapter 5. Similar stimuli can predict similar consequences: training: yellow light peck food reinforcement, test: presented with novel lights of different colors, rate of responding recorded for training and test. Discrimination: generalization gradient graph showing how physical changes in stimuli correspond to behavioral response changes, responding is highest for physically similar stimuli, responding is less for less similar stimuli.
